Abstract

The activation energy, E, of simple catalytic reactions over 3d-oxides and the initial heats of adsorption, Qads, of gases on metals are related in a complex way to the enthalpy of formation of oxides and to the electronegativity of the gases involved in the processes.

Abstract

Энергия активации, Е, простых каталитических реакций над 3d-окислами и начальная теплота адсорбции, Qads, газов на металлах связаны в виде сложной зависимости с энтальпией образования окислов и с электроотрицательностью газов, участвущих в реакциях.
